A fulvalene is a hydrocarbon obtained by formally cross-conjugating two rings through a common exocyclic double bond. The name is derived from the similarly structured fulvenes which lack one ring. Triapentafulvalene (3) is also known as calicene as in calix or chalice because of its wine-glass appearance.
